key notes :

🔬 What are Microorganisms?

  • Microorganisms are tiny living organisms that are not visible to the naked eye.
  • They include bacteria, viruses, fungi, protozoa, and algae.

🌱 Habitats of Microorganisms

1. In the Air

  • Microorganisms like bacteria and fungal spores are present in the air around us.
  • They can travel through dust, sneezes, and coughs.

2. In Water

  • Found in ponds, lakes, rivers, oceans, and even in boiling hot springs!
  • Algae and some bacteria thrive in water.

3. In Soil

  • Many bacteria and fungi live in soil.
  • They help in decomposing dead matter and fixing nitrogen for plants.

4. Inside the Human Body

  • Some microorganisms live in our mouth, gut, and skin.
  • Helpful bacteria in the intestine aid in digestion.

5. In Animals and Plants

  • Some microbes live inside animals and plants as symbionts or parasites.
  • Example: Bacteria in cow’s stomach helps digest food.

6. On Surfaces

  • Found on everyday surfaces like tables, door handles, and phones.
  • Need regular cleaning to prevent diseases.

7. In Extreme Environments

  • Some microorganisms, called extremophiles, live in:
    • Hot springs (high temperatures)
    • Deep oceans (high pressure)
    • Acidic or salty water
